Copositive Characterizations of Convex Hull Pricing
Madhusudan Ghosh, Antoine Lesage-Landry, Joshua Adam Taylor
Due to the nonconvex binary constraints of unit commitment (UC), no uniform linear pricing scheme supports the optimal dispatch. Convex hull pricing (CHP) and copositive duality pr…
Optimal Active Fault Detection in Inverter-Based Grids
Mohammad Pirani, Mehdi Hosseinzadeh, Joshua A. Taylor +1
Ground faults in converter-based grids can be difficult to detect because, unlike in grids with synchronous machines, they often do not result in large currents. One recent strateg…
Copositive Duality for Discrete Markets and Games
Cheng Guo, Merve Bodur, Joshua A. Taylor
Optimization problems with discrete decisions are nonconvex and thus lack strong duality, which limits the usefulness of tools such as shadow prices and the KKT conditions. It was…
Second-order Online Nonconvex Optimization
Antoine Lesage-Landry, Joshua A. Taylor, Iman Shames
We present the online Newton's method, a single-step second-order method for online nonconvex optimization. We analyze its performance and obtain a dynamic regret bound that is lin…
Attack Resilient Interconnected Second Order Systems: A Game-Theoretic Approach
Mohammad Pirani, Joshua A. Taylor, Bruno Sinopoli
This paper studies the resilience of second-order networked dynamical systems to strategic attacks. We discuss two widely used control laws, which have applications in power networ…
Predictive Online Convex Optimization
Antoine Lesage-Landry, Iman Shames, Joshua A. Taylor
We incorporate future information in the form of the estimated value of future gradients in online convex optimization. This is motivated by demand response in power systems, where…
